     146        In the instructions below, all the available drivers are built.  That
     147        will almost always work.  However, it is not efficient.  Depending on
     148        your video hardware, you probably need only specific drivers.
     149      </para>

     151      <para>
     152        The first thing you need to know is which type of video device you
     153        have.  In some cases it is built into the CPU.  In others is is a
     154        separate PCI card.  In either case you can tell what video hardware you
     155        have by running:
     156      </para>
     157
     158      <para>
     159        <command>lspci | grep VGA</command>
     160      </para>
     161
     162      <para>
     163        The video device is most likely one of three families: AMD, Intel, or
     164        Nvidia.  See the Command Explanations for 'gallium-drivers' below to
     165        see what options are available for your specific video hardware (or
     166        emulated video hardware).  You should probably add the swrast option as
     167        a backup driver.
     168      </para>
     169
     170      <para>
     171        For 'platforms' you can select x11 and/or wayland.  Note that in BLFS
     172        currently only Gnome and KDE can use wayland.  If you are not going to
     173        use one of those desktop environments then you probably only want x11.
     174      </para>
     175
     176      <para>
     177        For 'vulkan-drivers' you may want to limit the selection to your
     178        current hardware.  These drivers are used by some specific applications.
     179       
     180        For example, ffmpeg (including ffplay) will use Vulkan instead of
     181        OpenGL for rendering video on the GPU. If you do not want to do this
     182        you may or may not want to install them.
